The latest phpmyadmin automatically filled PmaAbsoluteUri in my already-existing config file and shouldn't have. I specifically had it blank, and PmaAbsoluteUri_DisableWarning set to TRUE, to allow autodetection. The machine only hosts one web server and reports it's canonicalname as a name on our web domain. I have not moved it from the localhost folder (it's not wrong - it also serves localhost). The machine reports it's name as something other than localhost though, so this action caused parts of phpmyadmin not to load. The main point is that webapp-config shouldn't have modified an existing config file. Reproducible: Always Steps to Reproduce:
It does not modify those config files unless you have specifically changed CONFIG_PROTECT_MASK. Please, post emerge --info and webapp-config version you are using and reopen.
I was indeed prompted by etc-update, but should it have changed it at all on an upgrade, is my point.
